+This is the source code for the Arduino OBD-II data logger, which displays (on a 128x64 OLED display module) and records (to a SD card) a selected set of OBD-II data. For hardware configuration and wiring guide, please refer to:
+http://obd.arduinodev.com
+
+The recorded data is stored in CSV format and the file can be illustrated into a graphic chart by a free service at:
+http://freematics.com/chart/
+
+To compile the code with Arduino IDE, please copy all library files from the libraries directory to Arduino's libraries directory.
